Method and apparatus are provided to prevent unneccessary execution of TCP/IP performance enhancing algorithms in a wireless communications network. The method includes monitoring acknowledgment message traffic between a sending unit and a receiving unit and preventing forwarding of an acknowledgment message to the sending unit when the acknowledgment message is a second duplicate acknowledgment message. The apparatus includes a first endpoint unit connected between a sending unit and a receiving unit. The first endpoint unit includes a monitor component to monitor acknowledgment message traffic between the sending unit and the receiving unit and a filter unit to prevent forwarding of a duplicate acknowledgment message to the sending unit until a predefined condition is met.
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
